UNITED STATES JAMES E. CALDWELL, OF FAYETTEVILLE, TENNESSEE.

BRUSH HEAD.

Application filed April 16, 1924.

To all whom it may concern:

Be it known that I, JAMES E. CALDWELL,

a citizen of the United States, residing at F ayetteville, in the Countyof Lincoln and State of Tennessee, have invented certain new and usefulImprovements in a Brush Head, of which the following is a specification.

This invention relates to new and useful improvements in brush heads andhas for its principal object to provide a simple and eflicient devicewherein the brush member may be readily removed and replaced by a newone when worn out.

A further object of the invent-ion is to provide abrush head of theabove mentioned character, wherein a pair of coacting members areassociated in such a manner as to provide means for receiving andclamping therebetween the bristles of a brush whereby the latter may besecurely carried by the brush head.

A further object is to provide a brush head of the above mentionedcharacter, which is simple in construction, inexpensive, strong anddurable and furthermore adapted for the purpose for which it isdesignated.

Other objects and advantages of this invention will become apparentduring the course of the following description.

In the accompanying drawing forming a part of this specification and inwhich like numerals designate like parts throughout the same Figure 1 isa side elevation of my improved brush head, and

Figure 2 is a central vertical section therethrough.

In the drawing, wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 1 designates generallymy brush head and the same comprises the body portion 2 which may beformed of any suitable material preferably aluminum, although I do notwish to limit myself to the particular kind of material of which thebrush head may be constructed. Provided in the upper portion of the body2 and arranged centrally therein is the downwardly tapering opening 3,the same being provided for the purposes of receiving the forward end ofa suitable handle (not shown).

The lower portion of the body 2 is cut Serial No. 706,950.

away as illustrated at 4 for substantially its full length and providedon the inner face of the cut away portion 4 are the vertically extendingrecesses 5, the same being arranged in spaced relation with respect toeach other in the manner illustrated in Figure 1 and for the purposeshereinafter to be more fully described.

Adapted to cooperate with the cut away portion 4: of the body 2 is theclamping plate 6, the inner face of which is also provided with aplurality of vertically extending recesses such as shown at 7 forcooperation with the recesses 5 provided on the inner face of the cutaway portion 4. The recesses provided in the inner opposed faces of thecut away portion and clamping plate respectively register with eachother to provide the sockets 8 in the bottom of the brush head for thereception of the upper ends of the separate bunches of bristles 9.

The upper ends of the bristles 9 are set in rubber and are vulcanized inthe manner well known in the art. For the purpose of holding thebristles in their respective sockets formed in the bottom of the brushhead, I provide the securing bolts 10 which extend through the upperportions of the clamping plate 6 and the cut away portion 4iof the body2 in the manner clearly illustrated in the drawing. Any number of theseclamping or securing bolts may be provided as is desired.

It will thus be seen from the foregoing description, that a brush headhas been provided wherein the brush member which comprises a pluralityof bristles may be readily removed from the sockets provided in thebrush head when the same have become worn out and may be replaced by newones by removing the clamping plate in the manner as is obvious from theconstruction shown.

The simplicity in which my brush head is constructed enables the same tobe manufactured at a very low cost, and the parts further so arranged asto permit the same to be readily disassembled or assembled without theloss of considerable time or labor.

While I have shown the preferred embodiment of my invention, it is to beunderstood that various changes in the size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention and the scope of the appended claim.-

Having thus described my invention, What I claim is A brush headcomprising a body portion having a handle receiving opening provided inthe upper portion thereof and arranged centrally therein, the lowerportion of the body portion being cut away, a clamping plate cooperatingwith the cut away portion, said cut away portion and the clamping platebeing provided with opposed cooperating recesses formed in the inneropposed faces thereof providing a plurality of sockets in the bottom ofthe brush head, a series of bunches of bristles having their upper endsdisposed in said sockets, and securing bolts extending through theclamping plates and the cut away portion.

In testimony whereof I afiix my signature.

JAMES E. CALDWELL.
